Moves the core geographic functions from $.simplicityGeoFn to
$.simplicity. Removes the old backwards compatible shims from
when each function was in global scope.

Changed:

    $.simplicityGeoFn.degreesToRadians -> $.simplicity.degreesToRadians
    $.simplicityGeoFn.radiansToDegrees -> $.simplicity.radiansToDegrees
    $.simplicityGeoFn.distanceRadians -> $.simplicity.haversineDistanceRadians
    $.simplicityGeoFn.distanceMiles -> $.simplicity.haversineDistanceMiles
    $.simplicityGeoFn.distanceKm -> $.simplicity.haversineDistanceKm

Removed:

    $.simplicityHaversineRadiusMiles
    $.simplicityHaversineRadiusKm
    $.simplicityHaversineDistanceRadians
    $.simplicityHaversineDistanceMiles
    $.simplicityHaversineDistanceKm
WIP Renames the widget JS files to be prefixed with "ui.". Concretely,
simplicityWidget.js is now ui.simplicityWidget.js.
